Pharmacological:
Is a
broad-spectrum antibiotic, its antibacterial spectrum,
antibacterial principles and application of tetracycline basically
the same. Many Rickettsia, Mycoplasma, Chlamydia, spirochetes,
amebic protozoa and some parasites are also sensitive to this
product. Enterococcus its resistance. Others such as Actinomyces
spp, Bacillus anthracis, Listeria monocytogenes bacteria,
Clostridium, slave card spp, Vibrio, Brucella spp, Campylobacter,
Yersinia bacteria sensitive to this product. The product of the
gonococcal and meningococcal certain degree of antibacterial
activity, but resistant to penicillin are also resistant Neisseria
gonorrhoeae to oxytetracycline. Over the years due to extensive use
of tetracycline, oxytetracycline resistance of common pathogenic
bacteria in the clinical phenomenon of serious, including
Staphylococcus aureus and other Gram-positive bacteria and the
majority of Gram-negative bacilli. Tetracycline antibiotic
cross-resistance between different species. This product mechanism
is that the drug can specifically with bacterial *0S ribosomal
subunit combination of A-position, inhibit the growth and impact of
the peptide chain bacterial protein synthesis. This product is on
the gastro-intestinal infections, including amoebic dysentery,
slightly stronger than the effect of tetracycline. And tetracycline
are closely cross-resistance.
